I had to take an upper division science elective as part of my cirriculum. I chose NATURAL DISASTERS as many students said it was a great class. It was fascinating, to say the least. I followed that with THE GEOLOGY OF NATIONAL PARKS AND MONUMENTS. If I discovered my interest in geology 20 years sooner, maybe I wouldn't be an accountant today. It's not about IF these events will happen, but WHEN. We still have to live our lives and enjoy. If I'm going to be taken out by a big earthquake and resulting tsunami, then that's my fate, but I'll never leave San Diego just to be safe. I'll take my chances living 3 blocks from the beach. With the global population increasing at an exponential rate, something will have to happen to curb it. Can you imagine the competition for food and water in 100 years? A major natural disaster might just be a blessing in disguise for the human race as long as it isn't an extinction level event.
